Hello,
I want to deploy a simple mail server so that it can be used for users to register themselves or reset passwords, etc.
Is there an easy one to deploy (in docker if possible) ?
I host my own mail. When it’s down, the mail just gets delivered after I get online again. Almost all mail servers are configured to retry over a period of several days before giving up.
Once my health insurer sent me mail by post to tell me that my mail server was down. That was kinda funny.
What if your home network goes down while you are away for a week and you cannot get it back online?
Not a risk I am willing to take, so a backup server would be required.
The longest outage I’ve had in a decade is when my primary SSD died a 2 months ago and I had to reinstall using config backups. It was down for around a day.
I’ve thrown a UPS on it and flown overseas for a week or two. It’s basically just email for me and the kids.
I’ve had longer outages on hosted services, TBH.
